Why does the weight of an object change in water?
because water weighs more than air, and there for, the weight difference between the water + object is less, making it seem as if the object has a smaller mass. Eg. Air = 0 (because we cant weigh it, so we set it as neutral) Water = 25 Object = 100 Object out of water = 100 Object in water = 75. Making it seem lighter
How much more does an object weigh after it has been submerged out of water?
Submerged "out-of-water". That is not possible. It is either submerged or it is out of water. Even when an object is submerger or partically submerged it will not weigh less. The physical characteristics (weight) of the object cannot be changed. The object, when placed in water will displace a certain amount of water and the object will float if the weight of the displaced water is more that the weight of the object. The object will then sink if it weighted more that the weight of the water it displaces. That said, the actual weight of the object doesnt change but if a scale were attached to it while hanging in air, it would read greater that when the object is floating or submerged in water.
Why you weigh more in the air than in the water?
because there is less gravity in water
Are objects lighter in water than in air?
They are not really lighter, they only seem lighter. Objects weigh the same in water as in air, but in the water, there is an additional force, of the water pushing the object up.
Why do objects weigh more in vacuum than in air?
Weight is dependant upon gravity and the relationship to large bodies of mass such as planets. However, if you were to be put into a vacuum on the surface of the Earth, you would way less. There is air pressure pushing down on you and that would add some weight. It also pushes up on parts of you. The difference is not likely to be very significant, but it should be measurable. However, I don't volunteer to be the person in the vacuum chamber! I am not a scientist, but I believe that you would weigh very slightly more in a vacuum. Think of our atmosphere as being a liquid of very low density compared with water. An object that floats in water displaces water in the amount of the object's weight; if you put a scale under a floating object, the scale registers the object's weight as zero. A perfectly bouyant object has the same density (specific gravity) as water, and as such will have a substantial weight if measured on land. But it will have no weight if weighed in water. An object that sinks in water will have weight, but it will weigh its land weight minus the weight of water displaced by its volume. This should be the same for a person (in a pressure suit, of course). The person will not be bouyed up at all by the atmosphere.

When you compare the density of water or air with another object how can you tell which has the lower or higher density?
-- If the object floats in water, then its density is less than the density of water. -- If the object sinks in water, then its density is more than the density of water. -- If the object floats in air, then its density is less than the density of air. -- If the object sinks in air, then its density is less than the density of air.

Do objects weigh more in the air or in water?
i think air, but I'm not sure I'm only 11
Object Weights more in air water vacuum or hydrogen?
ject weighs maximum in air ,hydrogen ,water, oil?
A stone weighs 9Newtons in air what does it weigh in water?
Need more info. Either the volume or density of the stone. From the info given all we know is that it will weigh less in the water than in the air.
What causes an object to weigh less when submerged in water?
An object seems to weigh less when submerged in water because the buoyancy of the water is greater than that of air, causing a force to be applied to the object, reducing the apparent net force that is required to support the object. However, gravity is gravity, and the object still weighs the same. Its just that there is an additional force acting on the object in opposition to the force of gravity. If you were to weigh a volume of water, and then weigh it again with an object in it, you would discover that the total weight did, in fact, increase by the weight of the object. Note that this is all independent of the object's mass. Mass and weight are two different things, and they should not be confused. The object's mass also does not change just because it is submerged in water. To illustrate this last point, an object in outer space does not weigh anything, because the net force of gravity is zero, but the object still has mass, and it requires the same force it always did in order to accelerate it at a certain rate.
Does a hot or cold object weigh more?
wow what a question!! well i don't know but hot air rises so cold would probably weigh more..
Why does something sink or float according to buoyancy?
Density (mass x volume) of the object. If the object is less dense (helium in air, or foam in water) than the fluid in which it is placed, it will float. Likewise, if the object is more dense (lead in water, or water in air), it will sink.
